Change format of $projects_list file from
<URI-encoded path> SPC <URI-encoded owner> LF
to
<URI-encoded path> SPC
<URI-encoded owner> [SPC <URI-encoded description>] LF
with optional project description. Please remember that only single
line of repository (project) description is supported. Note that SPC
can be replaced by any whitespace character.
This change required modifying git_get_projects_list() subroutine
(part when $projects_list is a file, not a directory to be scanned),
and git_get_project_description() subroutine.
The 'project_index' action creates projects list index file in the new
format, with project description. Also, it now does only minial level
of escaping / encoding.
While at it some comments describing changes and changed subroutines
were added, and information about $projects_list format was updated in
gitweb/README and in gitweb/INSTALL.

This version uses URI-encoded 'description' field in $projects_list
file, thus allowing to extend it (e.g. by adding categories support)
in a backward compatibile way.
Also, the format is described in more elaborate way; please comment...

You can generate the projects list index file using the project_index
action (the 'TXT' link on projects list page) directly from gitweb.
